GAS-LAMP.

To all whom "it may concern:

Be it known that I, FREDERICK J. HUM- rHREY, a citizen of the UnitedStates, re siding at the city of Kalamazoo, county of Kalamazoo, Stateof Michigan, have i11- vented certain new and useful Improvements in Gas-Lamps, of which the following is a specification.

This invention relates to improvements in gas lamps.

The main objects of this invention are: First, to provide an improvedgas lamp having inverted burners, which is of high efficiency. Second,to provide an improved gas lamp which is very quickly and easilyadjusted and cared for when in use. Third, to provide an improved gaslamp in which the number of burners can be readily changed and theuniform and finished appearance of the lamp preserved notwithstandingsuch changes. Fourth, to provide in a gas lamp of the inverted burnertype, improved means for supporting the burners. Fifth, to provide a gaslamp of the inverted burner type which is compact in structure andgraceful and attractive in appearance.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure l is a side elevation of a structure embodying the features of myinvention, the outer casing being shown in vertical section. Fig. 2 is adetail view, partially in vertical section, taken on a linecorresponding to line 22 of Fig. 3. Fig. 3 is a horizontal section takenon a line corresponding to line 3-3 of Fig. 2. Fig. 4 is a horizontalsection taken on a line corresponding to line 4lst of Fig. 2, a group offour burners being illustrated by dotted lines.

In the drawings, similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 is a gas de- Specifieation of LettersPatent.

I livery or gas supply pipe. At the lower l end of this I preferablyprovide a T-shaped coupling 2, from which depend the arms 3 and 4, thearm 4: being a dummy and the arm 3 a continuation or extension of thegas supply or delivery pipe. The chimney 5 is preferably mounted uponthe arms 3 and 4, a flange-like coupling member 6 being provided at theupper end of the chimney. The chimney is also preferably provided withan outwardly and downwardly-projecting flange-like portion 7 at itslower end.

Through one side of the chimney is an opening 8, through which the endof the burner tube 9 may be passed in assembling the lamp, the burnertube being curved or goose-neck in shape. The opening 8 is preferablyprovided with a closure 10 which, in the structure illustrated, issupported by the pivot 11 so that it can be swung to one side to permitthe introduction or removal of the burner tube 9. The closure 10 ispreferably provided with a notch 12 adapted to receive the burner tubeand closing onto the same so that the closure assists in supporting theburner tube in position.

The burner tube 9 is preferably provided with a plurality of burners 13,which are connected to the lower end of the tube by the branching arms14, the arms being grouped around the tube 9 so that the verticalportion of the tube 9 is located centrally of the chimney and theburners are grouped centrally within the flange portion of the chimney,as is illustrated.

At the lower end of the supply pipe is a valve casing 15, having anupwardly-projecting nozzle 16 thereon, a regulating valve 17 beingprovided for the nozzle. ()n the nozzle is a coupling member 18 havingair inlet ports therein, the ports preferably being of such size thatthe nozzle 17 can be manipulated through the same. The upper end of thecoupling member 18 is adapted to receive the end of the burner tube, seeFig. 2, and it thus assists in supporting the burner tube in position.The valve casing is arranged to project through the outer casing 20, thecasing being slotted at 21 to permit the adjusting of the casing when itis desired to have access to the parts within. The valve operatingmechanism for the main valve 23 and the pilot valve 24 is 011 theoutside of the casing. As the details of this operating mechanism formsno part of this invention, they are not described herein.

The outer casing 20 is adapted to rest upon the outwardly-projectingflange 25 mounted on the chimney. This is preferably in the form of aband adapted to embrace the flange portion of the chimney, as clearlyappears from the drawing, the upper end of the band being flaredoutwardly. The flange 25 is provided with air inlet openings 26 throughwhich the air passes from the outer casing to the globe 27, and thenceto the chimney and burners. The outer casing 20 is provided with airinlet openings 28 through which the air passes to openings 26 and to theburner tube. The globe 27 is supported on the globe band 29, which ishinged at 30 to the arm 31, depending from the casing support 25. Theglobe supporting band is held in its closed position by means of the pin32 which engages the arm 33. The details of this are not illustrated, asthey will be readily understood. The pilot burner 34 is preferablyarranged with its tip within the chimney, as is illustrated.

The mantles 35 are carried by the mantle support 36. This mantle supportis provided with a flange 37 at its edge, adapted to embrace the lowerend of the chimney. On this flange are pins 38 adapted to be inserted inslots in the chimney flange, not illustrated, and engaged by thering-like member 40 which is provided with bayonet slots 41. As thedetails of this mantle support form no part of the present invention,they are not illustrated herein, the mantle support being preferablythat described in the joint application of the applicant with Alfred II.Humphrey and Reginald lVright, filed July 13, 1908, Ser. No. 443,292.

To support the mantle support when it is released from the chimney, Ipreferably provide a supporting rod 42, which is arranged to bevertically and pivotally adjusted in a bearing 43 secured on the outsideof the chimney, so that when the mantle support is released from thechimney and dropped down, it can be swung to one side for con veniencein manipulation. To assist in centering and supporting the burners, theyare preferably provided with outwardly-projecting lugs 44 adapted toengage with the inwardly projecting lugs or members 45 on the chimney.This prevents the lateral swinging of the burners and assists incentering and holding them in position. I illustrate the lamp asprovided with three burners. These may be varied, as desired. Bysupporting the burners in this manner, the uniform and finishedappearance of the lamp is maintained throughout the variations,altllOlgh the number of burners may be var1e The mantle support shouldbe changed when the number of burners are varied, and to do this, it isonly necessary to remove the nut 46 from the supporting rod 42 andsupply a support adapted for the requisite number of mantles. Themantles can, however, be directly supported 011 the burner tips, as isthe common practice in inverted lamps.

The outer casing 20 is prefe'ably made up of band-like parts securedtogether, as is illustrated, the advantage of thus forming the samebeing that comparatively simple dies are required. The outer casing isadjustable to afford access to the parts of the lamp within. As aconvenient means for holding the casing in its elevated position Iprovide an arm 47 which is pivoted on the arm a to be swung out to serveas a rest for the casin By forming and arranging the parts as I haveillustrated and described, I secure a lamp having a plurality of burnerswhich is compact and graceful in appearance and very eliicient. Thestructure is very easily adjusted to the particular pressure and qualityof gas, a single adjusting mechanism answering for a plurality ofburners. Further, an even feed for the several burners is insured.

I have illustrated and described my improvements in detail in the formin which I have embodied them. I am, however, aware that they arecapable of considerable variation in structural details withoutdeparting from my invention but as these variations will readily occurto those skilled in the art to which this invention relates, I have notattempted to illustrate or describe the same herein.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent, is:
